导语：

暑假在家闲着无事，就琢磨着做一个web博客练练手，现在已经做完了，把过程分享出来给大家看看，分享一下学习经验。这是第二篇，主要讲node，webpack和vue-cli环境的搭建，使用vue全家桶，完成构建静态页面，写好路由。

一，前端组件的完结

1，顶部功能栏目

<template><div class="top"><div class="img_div"><img src="../../assets/logomin.jpg" class="img"><div class="text">轻松学算法</div></div><div class="tool"><div class="sign" @click="login" ref="sign" v-if="!islogin">登陆</div><div class="out" @click="logout" ref="out" v-if="islogin">退出</div><div class="more" @click="more">更多信息</div></div></div>
</template><script>export default {methods: {more() {this.$emit('more')},login() {this.$emit('login')},logout() {this.$emit('logout')}},computed: {islogin(){return this.$store.getters.getIsLogin}},
}
</script><style scoped>
.top{height: 50px;width: 100%;display: flex;background-color: #69d78a;position: fixed;top: 0;z-index: 1000;
}
.img_div{width: 180px;display: flex;margin: 5px 10px 5px 10px;
}
.img{height: 40px;width: 40px;border-radius: 20px;
}
.text{font-size: 14px;margin: 10px 0px 0px 20px;color: white;
}
.tool{display: flex;margin: 12px 10px 7px 50px;margin-left:auto;
}
.sign{margin-right: 10px;border: 1px white solid;padding: 4px 10px 5px 10px;border-radius: 15px;font-size: 14px;color: white;
}
.out{margin-right: 10px;border: 1px white solid;padding: 4px 10px 5px 10px;border-radius: 15px;font-size: 14px;color: white;
}
.more{border: 1px white solid;border-radius: 15px;padding: 4px 10px 5px 10px;font-size: 14px;color: white;
}
</style>

2，顶部导航栏

<template><div class="top-nav"><div class="img_div" ><van-icon name="arrow-left" size="24" @click="back" color="#ffffff"/><div class="text" v-html="text"></div></div></div>
</template><script>export default {props: {text: {type: String,default: ''}},methods: {back() {this.$emit('back')},like() {this.$emit('like')}},computed: {islogin(){return this.$store.getters.getIsLogin}},
}
</script><style scoped>
.top-nav{height: 50px;width: 100%;display: flex;background-color: #69d78a;position: fixed;top: 0;z-index: 1000;
}
.img_div{width: 180px;display: flex;margin: 13px 10px 5px 10px;
}
.text{font-size: 14px;margin: 2px 0px 0px 20px;color: white;
}
.tool{display: flex;margin: 12px 10px 7px 50px;margin-left:auto;
}
</style>

3，文章详情页面detail

<template><div class="article-new"><topnav @back= "back" :text= "text"></topnav><scroll  :probe-type="probeType":listen-scroll="listenScroll" ref="articleContentList"class="article-new-content"><div><div class="basicmessage" v-if= "showbasic"><div class="title">[两万字]面试官：听说你很懂集合源码，接我二十道问题</div><div class="imformation"><div class="time">2020-06-28</div><div class="viewnum">浏览量:{{hits}}</div></div><div class="author"><div class="imgdiv"><img  src="../../assets/logo.png" class="img"></div><div class="authorimformation"><div class="authorname">小米粥</div><div class="experience">码龄:3年</div></div></div></div><div class="sklentondiv" v-if= "!showbasic"><van-skeleton title :row="3" class="mysklenton"/><!-- <van-skeleton title avatar class="mysklentonavatar"/> --></div><div class="hr"></div><div v-html="compiledMarkdown" class="macked" v-if= "showmacked"></div><div class="sklentondiv" v-if= "!showmacked"><van-skeleton title :row="3" class="mysklenton"/><!-- <van-skeleton title avatar class="mysklentonavatar"/> --></div><div class="hrweight"></div><commentarea v-if= "showcommentarea" :list= "commentcontent"></commentarea><div class="sklentondiv" v-if= "!showcommentarea"><van-skeleton title :row="3" class="mysklenton"/><!-- <van-skeleton title avatar class="mysklentonavatar"/> --></div><div class="hrweight"></div></div></scroll><comment @commentsubmit= "commentsubmit" @like= "like" @good= "good" :infogood= "infogood" :infolike= "infolike":goodnum= 'goods' :likenum= "likes"></comment></div>

}
</script><style scoped>
</style>

使用了mark去解析.md，并且使用highlight.js把代码部分进行高亮化处理，使得代码阅读变得更加舒服。

二，路由的编写

import Vue from 'vue'
import Router from 'vue-router'
import home from '@/components/home/home'
import article from '@/components/article/article'
import me from '@/components/me/me'
import article_group from '@/components/article_group/article_group'
import article_detail from '@/components/article_detail/article_detail'
import article_new from '@/components/article_new/article_new'
import like from '@/components/like/like'
import imformation from '@/components/imformation/imformation'
Vue.use(Router)export default new Router({mode: 'history',routes: [{path: '/',redirect: '/home'},{path: '/home',name: 'home',component: home,children: [{path: ':id',component: article_new,}]},{path: '/article',name: 'article',component: article,children: [{path: ':id',component: article_group,children: [{path: ':id',component: article_detail}]}]},{path: '/me',name: 'me',component: me,children: [{path: 'like',component: like,children: [{path: ':id',component: article_detail}]},{path: 'imformation',component: imformation}]}]
})

前端主要是三个主界面，以及一些子组件的构成，运用children子路由，去写好整个应用的路由关系。并且使用路由传参，让子路由拿到信息去调用api接口。

你们的赞就是对我最大的鼓励。谢谢~
